DESCRIPTION:\nThe Anderson model is a Schroedinger operator with a random 
 potential. It is used in several areas of physics to describe quantum syst
 ems with impurities. The main question here is about the character of the 
 spectrum of such an operator\; the main issue is pure point (insulation) v
 ersus absolutely continuous (conductivity). The Anderson tight binding mod
 el is set\non a lattice\, and a standard assumption about the potential is
  IID. The model generated a vast literature but so far it was almost exclu
 sively about a single-particle system. Recently\, Chulaevski and myself\ns
 tarted a project aiming multi-particle systems. I'll report on our progres
 s so far. No preliminary knowledge of quantum mechanics or spectral theory
  will be assumed.\n
